Need some help on a complicated form project

I have an interesting project I'm attempting. I was wondering if there was anyone out there who can assist.

I'm creating a catalog pdf which will allow you to enter desired order quantity as the user browses through the catalog pages. My ultimate goal is to have the quantity information entered in one document (containing the catalog), some how cross-linked into a separate order-form document. So, if someone would like to order 50 copies of a particular book, they can do so on the fly (on the actual catalog page) and then generate an order form existing in a separate document that can then be submitted as a PDF file. We would need the order form in separated document for emailing purposes. Is this a job for java script? I forgot to mention that most of the end users will be using Adobe Reader not writer.

One other thing-- is there anyway to change the format of the submitted data? When I tested submitting a form in the FDF format and then generating a csv file, the form field information reads horizontally. this is very confusing.

Example:
form1.csv title price isbn name billto shipto qty

I would like it to read vertically.
form1
tile
price
isbn
name
billto
shipto
qty
